Recommended Speaker List for Atma-Sphere OTL Amplifiers.

Thank you very much, Clio09. I don’t mind my Jazz Modules being replaced by Quad 57s + swarm! Very nice combination.

Dragon, thank you for having considered my speakers.

Cosmetically they certainly are not exotic, nor do they use any particularly exotic technology in the drivers, aside from optional Beryllium diaphragms for the compression drivers. I now have access to a master woodworker who has built T-7s for John Wolff, so I can offer excellent cabinetry on a custom basis, but he is not cheap.

Speaking of which, have you considered the T-7? Field coil motor, wizzerless fullrange cone, beautiful tonal qualities, and magnificent cabinetry.

I don’t know whether this would be "exotic", perhaps merely "unorthodox", but some of my models deliberately approximate the acoustic effects of being in a significantly larger room, which imo has psychoacoustic benefits.

If you are serious about hearing what I do, I would like to put you in touch with a colleague of mine who a) has more of my designs on hand than I do; b) has a much better audition set-up than I do; and c) has contributed ideas which have significantly improved my designs.  I spoke with him just a few minutes ago and he'd enjoy it very much.

I've been designing speakers with Ralph's smaller amps (S-30 and M-60) very much in mind for years, but my speakers tend to be bigger than average (though usually not "T-1.5 big").  I do horn speakers that hopefully don't sound like horns, well at least not in the negative ways that the word "horn" can bring to mind.   

In a fairly compact speaker, you might consider High Emotion Audio and Omega Loudspeakers. 

At what they do well the Quad 57s are just magnificent.  If you decide to do a stacked pair, contact me for a tweak suggestion.

Best of luck in your quest,

Duke
